Value Collection 34889 Pull Out Dowel Pin 1/4x1.5in Alloy Steel

Product Description

The VALUE COLLECTION 34889 is a standard pull out dowel pin manufactured from alloy steel to Grade 8 specifications and conforming to ASME B18.8.2. The pin measures 1/4 inch in diameter and 1.5 inches in overall length, with a diameter tolerance of 0.0002 inches for precise fit in close-tolerance holes. One end is beveled and the opposite end is rounded, which facilitates installation and extraction in production fixtures, jigs, and mechanical assemblies. Rockwell hardness runs C 50-58, providing resistance to wear and deformation under repeated use. Machinists, toolmakers, and maintenance technicians install these pins to locate and align mating components with repeatable accuracy.

Standard pull out dowel pins of this type are used in manufacturing fixtures, press tooling, machine bases, and general mechanical assemblies where precise component alignment is required. The beveled end aids driven installation while the rounded end allows engagement with a puller or extraction tool. These pins are suited for both light-production and maintenance applications across metalworking, industrial equipment, and mechanical fabrication environments. Sold in a package quantity of 25, making them practical for shop stock or repeat-use tooling builds.

Key Features

• ASME B18.8.2 standard compliance ensures dimensional interchangeability with conforming tooling
• Grade 8 alloy steel construction with C 50-58 Rockwell hardness for wear resistance
• One beveled end and one rounded end for driven installation and mechanical extraction
• Diameter tolerance of 0.0002 inches supports close-tolerance locating applications
• Package quantity of 25 supports shop stocking and multi-fixture builds

Compatibility

Designed as an OEM-style replacement or standard stock pin for any application requiring a 1/4 inch diameter, 1.5 inch length pull out dowel pin conforming to ASME B18.8.2.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a press or mallet with an appropriate driver. Ensure the receiving hole is reamed to the correct tolerance before driving the pin to avoid galling or bore damage. Use a puller or slide hammer against the rounded end for extraction to avoid damaging the bore or surrounding component. Follow applicable facility safety and lockout-tagout procedures when servicing live machinery.
